G4[TI] is an upgraded version of the G4[TD] Visible Light Facial Recognition Terminal with Temperature Detection using intelligent engineering facial recognition algorithms and the latest computer vision technology. Based on the existing firmware and hardware configuration of G4[TD] as well as the mighty computing power and facial recognition algorithm, the terminal integrates a large resolution thermal imaging module with Computer Vision facial recognition system. G4[TI] supports facial recognition with large capacity and speedy recognition and other authentication methods, including identification with fingerprint, card, and password. G4[TI] improves security performance in all aspects. G4[TI] adopts touchless recognition technology and new functions, namely body temperature detection and masked individual identification. Without requiring physical contact with surfaces that might have contaminated significantly reduces the infection risk. G4[TI] is also equipped with an ultimate anti-spoofing algorithm for facial recognition against almost all types of fake photos and videos attack. Through the fast and accurate body temperature measurement and masked individual identification functions, G4[TI] is a perfect choice to help reduce the spread of germs and help prevent infections straightly at each access point of any premises and public areas, such as hospitals, factories, schools, commercial buildings, stations. If the function mentioned above cannot satisfy customers' needs, we can provide an EDK embedded development kit and adjustment tools. Based on our robust and stable platform, the client's R&D team can quickly develop, integrate, and debug the entire embedded system.
